2. Protect the liver. Protein in eggs can repair liver tissue damage. Lecithin in egg yolk can promote the regeneration of liver cells, increase the amount of human plasma protein, and enhance human metabolism and immune function.
3. Prevention and treatment of arteriosclerosis. American nutritionists and medical workers used eggs to prevent and treat atherosclerosis and achieved unexpected and amazing results.
4. Prevent cancer. Eggs contain more vitamin B2, which can decompose and oxidize carcinogens in human body. Trace elements in eggs, such as selenium and zinc, also have anti-cancer effects.
5. delay aging. Eggs contain almost all the nutrients needed by the human body, so they are called "ideal nutrition banks". Nutritionists call it the "complete protein model", which is one of many people's longevity experiences.
Eat eggs wisely
The most nutritious cooking method:
There are many ways to eat eggs. In terms of nutrient absorption and digestibility, boiled eggs are 100%, scrambled eggs are 97%, tender fried eggs are 98%, old fried eggs are 8 1. 1%, boiled eggs with boiled water and milk are 92.5%, and raw eggs are 30% ~ 50%. From this point of view, boiled eggs are the best way to eat, but pay attention to chewing slowly, otherwise it will affect absorption and digestion. But for children, steamed egg soup and egg drop soup are the most suitable, because these two methods can loosen protein and be easily digested and absorbed by children.
Note: eat less tea eggs, because tea contains acidified substances, which combine with iron in eggs, stimulate the stomach and affect the digestive function of gastrointestinal tract.
Eggs (of hens)
How much do you eat a day?
Eggs are high-protein foods. If you eat too much, it will lead to an increase in metabolites and increase the burden on the kidneys. Generally speaking, there is one for children and the elderly, and two for teenagers and adults.
Is egg white better or egg yolk better?
The correct way to eat is to eat the whole egg. Protein contains more protein, while other nutrients are egg yolk.
Egg misunderstanding ABC
Myth 1: The more eggs a woman eats, the better.
In the process of delivery, the maternal physical exertion is great, the digestion and absorption function is weakened, and the detoxification function of the liver is reduced. After eating in large quantities, the burden of liver and kidney will increase, resulting in adverse consequences. Excessive intake of protein will also produce a lot of ammonia, hydroxyl, phenol and other chemicals in the intestine, which is very toxic to human body, prone to abdominal distension, dizziness, limb weakness, coma and other symptoms, leading to "protein poisoning syndrome". Protein's intake should be calculated according to protein's digestion and absorption function. Under normal circumstances, it is enough for pregnant women to eat about 3 eggs a day.
Myth 2: Eating eggs often leads to high cholesterol.
No, because egg yolk is rich in lecithin, which is a powerful emulsifier. It can make cholesterol and fat particles extremely fine and pass through the blood vessel wall and be fully utilized by cells, thus reducing cholesterol in the blood. Moreover, lecithin in egg yolk can release choline after digestion, and then enter the blood to synthesize acetylcholine, which is the main substance of neurotransmitters, which can improve brain function and enhance memory.
Myth 3: Raw eggs are more nutritious.
Eating eggs raw is not only unsanitary, but also easy to cause bacterial infection, and there is no nutrition. Raw eggs contain avidin, which affects the absorption of biotin in food and leads to "biotin deficiency" such as loss of appetite, general weakness and muscle pain. In addition, raw eggs contain "antitrypsin", which will destroy the digestive function of human body. As for those "hairy eggs" that have hatched but have not hatched chickens, it is even more unsanitary.
Cooking, all kinds of decryption
Spread eggs: avoid fire, or you will lose a lot of nutrition. Because when the temperature is too high, protein in eggs will be destroyed and decomposed. Especially dark eggs and fried potato chips will lose more nutrients. But the fire is too small. After a relatively long time, the water will lose more, and the spread eggs will dry, which will affect the texture. So it's best to spread eggs over medium fire.
Steamed egg custard: whether the egg custard can be steamed well depends mainly on whether the egg liquid is stirred evenly, except for putting proper amount of water. When stirring, the air should be mixed evenly and the time should not be too long. Temperature is also directly related to the stirring of egg liquid. For example, when the temperature is below 20℃, the stirring time is longer (about 5 minutes), so that there are holes of different sizes invisible to the naked eye after steaming; When the temperature is higher than 20℃, the time should be shortened. Don't put oil and salt in the egg at first, which will easily destroy the colloid of the egg and make the steamed egg soup thick and hard; If you stir the egg mixture evenly, then add oil and salt, stir it for a few times and put it into the steamer, and the custard will come out very soft.
Beat the egg drop soup: add a few drops of vinegar when the soup is boiled, and the egg drop juice will look beautiful when it enters the water. Boiled eggs: It is very important to master the time, generally 8 minutes to 10 minutes is appropriate. If cooked too raw, protein is not loose, and it is not easy to digest and absorb. If it is overcooked, the structure of protein changes from loose to tight, and it is also not easy to be digested and absorbed.
Special note: Do not add monosodium glutamate to scrambled eggs.
Eggs themselves contain a lot of glutamic acid and a certain amount of sodium chloride. If monosodium glutamate is added, these two substances will generate a new substance-sodium glutamate, the main component of sodium glutamate, and the umami taste of the egg itself will be covered up.
